3.2.4.3 Scaling of internal units for the fieldbus ("factor group")
The "factor group" and user unit depend directly on each other. If the unit in the "factor group" is
changed, the user unit also changes and vice versa. The prefix in the "factor group" used for scaling
has no influence on the internal depiction of the parameters in the servo drive. The units are scaled to
user units according to the CiA 402 specification ("factor group"). Scalability is limited to the power of
10.
Different user units cannot be set for position, velocity, acceleration and jerk. When the user unit is
changed, the derivations are changed as well.
Parameters for the scaling of internal units for fieldbus
ID Px. Parameters Description
Determines the resolution of the position. The value is inter-
preted as ten-expont e.g. with meter and -6 the resolution is 1
µm.
Access read/write

7841 Resolution position
Unit −
Determines the resolution of the velocity. The value is inter-
preted as ten-expont e.g. with meter and -3 the resolution is 1
mm/s.
Access read/write

7842 Resolution velocity
Unit −
Determines the resolution of the acceleration. The value is inter-
preted as ten-expont e.g. with meter and -3 the resolution is 1
mm/s².

7843 Resolution accelera-
tion
Unit −
Determines the resolution of the jerk. The value is interpreted as
ten-expont e.g. with meter and -3 the resolution is 1 mm/³.
